Supersymmetry for Gauged Double Field Theory and Generalised Scherk-Schwarz Reductions

Understand

Previous constructions of supersymmetry for double field theory have relied on the so called strong constraint.

• In this paper, the strong constraint is relaxed and the theory is shown to possess supersymmetry once the generalised Scherk-Schwarz reduction is imposed.
• The equivalence between the generalised Scherk-Schwarz reduced theory and the gauged double field theory is then examined in detail for the supersymmetric theory.
• As a byproduct we write the generalised Killing spinor equations for the supersymmetric double field theory.
